Suppose 4th grade children are exposed to a reading intervention program designed to improve scores on a reading assignment. Children were given a pre-test and a post- test to assess their reading skills before and after the reading intervention. Find a 95% confidence interval for the mean difference in scores on the assignment. (Round each number to decimal places.) We are 95% confident that the mean difference in reading scores from the pre-test to the post-test for all 4th graders in the population is between type your answer... and type your answer.. 3 points
